For the placing of electrical engineering components in CAD the following shall apply:

I. Octant has positive x,y and z axis

Connection point at left, lower, back edge of bounding box

In order to get a proper placement of part in most cases it will be necessary to shift the part along X, Y and Z axis.

You can realize shift and rotation via dialog Fixed plane.

The following exemplary figure shows a part where the orientation is correct (Z upwards), so that only a shift has to be performed (see entries under Base point). As the Z axis shows upwards, no rotations of axes have to be performed. The input fields under X axis retain the default values 1,0,0. The input fields under Y axis retain the default values 0,1,0.

The Base point of absolute plane is in the left, lower, back edge of the bounding box.

The connection point can be set with Angle 0, as no rotation is necessary or rotations are realized via plane.

	Note
	The name of connection point can freely be chosen (in this example "CP_Orientation").

The coordinates of connection point under "Position" can be left at 0,0, so that the connection point is in the Base point of plane.

Set connection point

	Note
	Alternatively, a needed shift can also be performed here in the sketch instead via dialog Fixed plane -> Base point.

For parts with wrong orientation you have to perform respective adjustments in the dialog Fixed plane under X axis and Y axis.

After transformation (rotation + shift) applies:

Example with rotation: The transformation happens with 2 rotations.

The original X axis is mapped to the Z axis (Z=1) and then the original Y axis to the X axis (X=1).

Original coordinate cross and newly oriented coordinate cross of connection point

Result in E3

Model Properties - Correct orientation of axes and marked connection point

In an exported PS3 file you can check orientation and shift of connection point:

Now the Connection point has to be classified.
